This game is a ton of fun! I loved every minute of it...
Sam Fisher becomes more than just another spy... he has his own motives, but underneath it all he's a patriot and will do whatever he can to further the US of A... I love that.
I do have to point out that this game isn't completely realistic... I don't see how you could be standing infront of someone and they can't see you or hear you breathing... unless it was pitch black, as in a mile deep in a cave were the sunlight never touches the walls dark..
